PHoToGmPHIC-PBINTING mask..

Application med October 2, 1915.

To ali whom it may oom-ern.'

Be it known that we, GUY A. Tonny and WILLIAM A. FLOWER, citizens of theY lnited States, residing at Twin Falls, in the county of rfwin Falls, State of Idaho, have invented a new and useful Photographic-Printing Mask, of which the following is a specification.

The present invention appertains to photographic printing masks, and aims to provide a mask of that character provided with novel means whereby various numbers or identification marks may be provided upon the margins of the prints durin the printing operation, whereby the prints after being fixed, washed and dried can be readily sorted without the necessity of comparing the prints with the negatives as customary.

It is the prevailing practice in making prints from negatives to fix.A wash. dry and trim the prints altogether, which requires the various groups or jobs to be assorted bv 'comparing the prints with the negatives,

and which involves more or less confusion and trouble. Vith the present mask, each group of prints or job has an individual number or identification mark provided upon the prints at the time ofth'e exposure thereof. So that when the prints have been washed and dried. the)1 can be readily assorted simply by using the identification numbers or marks. these identification numbers or marks being cut ofi when the prints are trimmed.

Another object of the invention is the provision of a photographic printing mask of the nature specified. whereby the identificationl number or mark to be provided upon the print can be changed readily, so that various jobs can be assigned different numbers or marks.

ft is also within the scope of the invention to provide an improved mask having the above characteristics. and which at the same time is simple and inexpensive in construction, which can be used in ordinary printing frames and machines. and which is practical, convenient..serviceable and efficient in use.

Spcccation of Letters Patent.

Serial No. 53,810.

the details of construction hereinafter deY scribed and claimed. it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed with out .departing from the spirit of the invention.y

The invention is illustrated in the accompanying drawing1 wherein:-

Figure l is a plan view of one form ot mask. Fig. 2 is a section thereof taken on the line 2-2 of Fig. l. Fig. 3 is a plan vier' of another form of mask. Fig. is a section on the line -l-i of lfig. 3. Fig. .3 is a plan view of a second modification. Fig. fi is a section on the line f---f of Fig.

In carrying out the invention. reference being had particolari)v to Figs. l and 2. there is provided a mask 1 of an)v suitable :size

and contour. and havin a suitable o eninfr vis provided at one .side or adjacent one. edge of the opening 2 with two pairs of parallel slits 3 forming bridging portions or straps 4 suitablyY spaced apart. The mask l is also provided with a suitable aperture?, between the straps 4. A strip 6, preferably of the same material as the mask 1, is disposed slidahly upon the mask and passes slidably under the straps 4 which are offset from the bod)r of the mask to guide the strip (3 for longitudinal movement. the endsof the strips f3 pro allow the strip to be slid or adjusted longitudinally by the fingers. This strip 6 has a trading from the straps 4 to cured to that side ,of the mask 1 opposite the Yclose the other identification numbers.

1straps 4, to close the slits 3, and to also reinforce the mask 1 where it is slitted.

Then one set of prints is being made, the strip 6 is adjusted to bring the selected number or mark 7 over the aperture', and then when the sensitized paper is exposed, the light rays will pass through the identi ication number over the aperture 5 and through the aperture, but the mask e proper identification number is thus printed upon the sensitized paper at the margin of the print. When a new job is taken up,

the strips `l is shifted to bring a new iden.

tificatiori.'fnumber over the aperture 5. When the several strips of prints are fixed, washed and dried in a mixed condition, they can iie readily assorted by means of the identification marks, and without the necessity of comparing the prints with the negatives as usual. This saves lconsiderable time and trouble. The identification mar are provided upon the sensitized paper at the same time that the paper is exposed for purpose of printing, so that the present invention will not involve additional work, it only being necessary to adjust the strip 6 when the new jobs are taken up.

The second form of the invention illustrated in Figs. 3 and 4 is used for the same purpose, but is of slightly different construction, The mask l'lwhich is provided with the opening 12 has a pair of slits 13 at one side of the opening 12, and prefer ably parallel with the respective edfre of the opening. These slits 13 provide Va tbridging portion or strap 14, and a pair of disks 16 are disposed upon the body portion of4 the mask 11 under the stra 14, said strap holding the, disks against tiie body of the mask. The mask 11 is provided with an aperture 15 for each disk 16 over which the marginal portion of the disks or disk project, the marginal portion of each disk having an annular series of identification numbers or marks 17 formed by slotting or perforating the disk to allow the light rays to pass through the perforated or slotted portions. The disks 16 are mounted for rotation between the body of the mask and the strap the disks and the straps 14; The disks 16 are preferably overlapped to bring them closer together. The mask l1 and disks ifi may bc constructed of the same materials as the mask 1 and strip (3, and any suitable number of disks 1f) may be employed according to the number of jobs which are liable to require completion at the same time. Each disk has identification numbers running from 0 to i), and each disk also has a blank portion adapted to be moved over the respective aperture l5 for preventing the light from passing through the aperture, and with the two disks 16, it is possible to use identification numbers from 0 to 99, by properly rotating the disks as will he apparent without detailed description.

In the variation illustrated in Figs. 5 and (i, the identification numbers or marks are provided in the mask itself, while theI mov able member carried by the mask is provided with the aperture. The mask 21 has the opening 22, and opposite pairs of slits 23 at one side of said opening providing the straps or bridging portions 24 through which a pair of parallel strips 26 are slidable. The strips and mask areiconstructed ot the same materials as the masks and movable parts carried thereby above described, the strips 26 being disposed 'upon the mask and passing under the straps 24. The identification numbers or marks 27 are provided in the mask 2l between the pairs of slits 23, and each of the strips is provided with an aperture 25 between the straps 24. By

vmoving the straps 26, the apertures may be brought over the desired identification.

numbers, while the others are closed. This is a reversal of the structure disclosed in Figs. 1 and 2, and its utility will be readily understood from the foregoing.

Having thus described the invention, what is claimed as new is:

l. ,X photographic printing mask having an aperture and having a pair of siits proyin succession, the mask having a pair of slits providing a strap and the movable member being disposed between the body of the mask and said strap to hold it in place.

3. A photographic printing mask, and a movable member disposed thereon, one of said parts having a series of identification lso mark providing portions and the other having,r :1n :lpmtiuc for exposing Said portions in slwoossion, the musk having a strap, und said movable nwmbel being disposed betwcon said Strap and the body of the mask to be hold in piace against the mask by the strap.
